By the end of 2024, the global total deployment of 5G base stations reached 6.37 million units. The Chinese market has played a significant role in this progress. 5G base stations have introduced Massive MIMO technology, using 32T32R and 64T64R RF units to cover mid-frequency application demands in the 3-6GHz band. This enables users to enjoy high-speed uplink and downlink wireless communication experiences even in densely populated areas such as office buildings and stadiums.
Based on an average single-channel power of 5-10W, the RF front-end systems of base stations typically operate in scenarios with 300W and higher power, imposing stricter requirements on the high-frequency, high-power, and heat dissipation characteristics of RF devices. Wide-bandgap compound semiconductors like GaN demonstrate significant advantages in RF chips manufacturing.
